EAST NEWARK, NEW JERSEY, A CORPORATION OF NEW SHADEROLLER.

Patented Oct. 24, 1916.

Application filed April 30, 1915. Serial No. 24,855.

which the following is a specication.

This invention relates to improvements in means for attaching shades to metallic rollers, and is a modification of the invention disclosed and claimed in my co-pendingapplication for patent liled on even date herewith, Serial Number 24,8545 designated as Case A.

The objects I have in view are: First: to attach the shade to the roller without the use of tools. Second: to facilitate the introduction of the shade into the groove of a roller without the need of folding or creasing the end of the shade. Third: to accommodate dierent thicknesses of shades. Fourth: to accommodate irregularities in manufacture. Fifth: to facilitate the removal of the shade when desired from the roller without the use of tools. These and further objects will more fully appear from the following specification and accompanying drawings in whichl V Figure 1 is an elevation of a roller and shade and a plurality' of attaching devices embodying the invention in position. Y The shade and roller are broken away intermediate the ends thereof. The view illustrates two attaching clips, one in locked position and one in unlocked position; Fig. 2 is a sectional view, on an enlarged scale, of the roller and shade shownvin Fig. 1, the clip being in unlocked position; Fig. 3 is a similar view, showing the clip in position; and Fig. L1 is a perspective view of a clip embodying the invention.

In all views like parts are designated by the same reference characters.

In carrying out my invention, I utilize a shade roller 1 which is preferably made of metal, tin for example. This Vshade roller is provided with a longitudinal groove 2 In cross section the groove is dovetailed; that is to say, the sides 3 and l are inclined and the bottom 5 is preferably flat. This makes a groove which is narrower at its top than at its base. The shade 6 is introduced, preferably with its raw edge 7, in one corner of the groove, for exampleadjacent the side 4, as illustrated. So much of -inbefore described,

l and will hold the the structure as already described is identical with that disclosed and illustrated in my copending application for patent hereinbefore referred to. The clip about to be described and its manner of introduction and removal are different. The clip 8 is made preferably of sheet metal. Elastic or spring material may be employed. The clip has a cross member 9, depending legs 10 and curved feet 11. Preferably all these parts are made out of a single piece of metal, as shown in Fig. et. The cross member. 9 is preferably somewhat narrower than the groove 2. The length of the depending legs 10 is such that the curved feet 11 may rest upon the bottom of the groove and the cross member 9 will then be above the plane of the upper edge of the groove, as shown in Fig. 2.r The distance separating the curved feet 11, 11 is about the width of Jthe bottom of the groove or a little greater, as will be hereinafter described. After the edge of the shade G has been introduced within the groove, against one corner thereof, as shown in the drawings, for example in the corner adjacent the side al., as herethe clip is then introduced as shown in Fig. 2, and to the right in Fig. 1, pressing the shade down into the groove. Vhen in this position the cross member 9 lies at right angles to the axis yof the roller. This cross memberk is now rotated by force applied to the cross member so that it assumes a position which is longitudinal to the roller as shown in Fig. 3 and to the left of Fig. 1. The effect of this rotation is to bring the curved feet 11, 11 into contact with that portion of the shade which is adjacent to the sides 3 and 4: of the groove.

If the clip is made of spring metal or other suitable elastic material the distance separating the curved feet 11, 11 willbe designed to be somewhat greater than the width of the bottom of the groove. Vhen the clip is introduced into the groove and twisted to final position, the depending legs 10 will thereby be slightly distorted and the curved feet will be held with elastic pressure against the shade. Owing to the inclined shape of the sides of the groove, the engagement of the feet with the groove will tend to force the clip into the base of the groove and hold the shade in position. The shade will roll up on the cross members 9 latter and keep them from turning. It is 'apparent that if it isi desired to remove the shade it is but necessary to turn or twist the clips about 9() degrees so thatthe cross members are substantially at right angles to the longitudinal axis of the roller. This Will place the legs 10, l0 in line With the groove and the clips may be removed, and there being nothing else to hold the shade in position, it may be removed. y

It is to be understood that the raw edge of the shade need not be introduced Within the groove. If desired, the shade may be first creased and doubled over, and the creased edge may be introduced, or a portion of the shade removed from the edge may be inserted into the groove, if desired. It is also to be understood that the member S) need not extend an equal distance beyond the legs l0, 10, as illustrated, as it may extend a greater distanceon one side than the other, or it may extend on one side only.

lVhile the device is preferably made of spring sheet metal,it is not necessarily so made, as other suitable materials can be employed.

It is to be unders ood also that the shape of the feet may be different from' those illustrated in that they need not be curved. Also the legs m-ay be different. For example but a single leg need be used with feet being carried by it, but this construction is not preferred.

Inaccordance with the provisions of the patent statutes, I have described the principle of my invention, together With the apparatus WhiclrI now consider to represent thebest embodiment thereof; but I desire :to have it understood that the apparatus shown is merely illustrative and that the invention may be' carried out in other Ways. f,

Having now described my invention, What I claim as new and desire to secure by Letters Patent is n Y l. A clip for securing a Window shade to far'grooved roller, which comprises a device Y with a plurality of feet projecting in opposite directions adapted to engage With the shade Within the groove and having means outside the groove for rotating the device `when the same is in position on the roller.

2." A olipfor securing a Window shade to a shade roller having a dovetailed groove therein, which comprises a device adapted to engage With the shadeat the base of the therein,

leach foot having its groove, said device having an operating member located outside the groove When the device is in position on the roller, a body projecting from the member and a foot projecting from the body, said foot being adapted to enter the groove While the inemer is in one position and adapted to be locked Within the groove when the member is turned at right angles to the first mentioned position.

8. A clip for securing a Window shade to a shade roller having a dovetailed groove therein, Which comprises a device adapted to engage With the shade at the base of the groove, said device having an operating member located outside the groove when the device is in position on the roller, a body projecting from thel member and feet projecting from opposite sides of the body and at right angles thereto, said feet being adapted to enter the groove While the member. is in one position and adapted to be locked Within the groove when the member is turned at right angles to the rst mentioned position.

,4. The combination with. a shade roller, havinga longitudinal dovetailed groove, a shade, and a removable clip, said clip comprising a member lying outside of the groove and substantially parallelv With the longitudinal axisof the roller whereby the engagement of the shade Will prevent rotation of the clip, and two legs extending into the groove, each leg having Va foot at an angle thereto Which engages With the shade and forces itinto Contact with the inclined sides of the groove.

5. A clip for securing a Window shade to a shade roller, having a dovetailed groove Which comprises an elongated member extending longitudinally of the roller, and adapted to be engaged beneath the shade when the latter is Wound upon the roller, a leg on each side of the member, said legs being perpendicular to the member, a foot perpendicular to each leg, the feet extending beyond to the edges of the member and at right angles thereto,

outer end rounded.
